BATH FOR RAZOR-HON ES.

No Drawing. Original application filed March 13, 1912, Serial 110,683,595.

Specification of Letters Patent.

Patented Mar. 31, 1914. Divided and. this application filed October 30, 1912. Serial No. 728,681.

To all whom it may concern Be it known that I, JOHN E. CLARK, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Baths for Razor-Hones, of which the following is a specification.

My invention relates hones, this application being a my copending application, 683,595, filed March 13, 1912.

My above named application disclosed a method of treating razor hones by immersing the same in a suitable oleaginous bath, while this present application covers the composition of said bath.

The object of the present invention is to provide a bath in which the hone may be immersed and which will render a hone so treated, smooth and non-gritty.

\Vith this object in view, I provide a bath consisting of a solution of saponaceous matter in an oleaginous solvent.

More particularly this bath consists of a solution of soap, preferably a good quality shaving soap,

to a bath for razor division of Serial No.

in spirits of turpentine, the proportions preferably being one pint of spirits of turpentine to six ounces of soap. In forming the bath, the soap is cut or otherwise divided into small pieces and added to the turpentine and the mixture is then heated to the boiling point. The solution thus formed is then ready for use and may be bottled to prevent evaporization until used.

"When a hone is to be treated with this bath or mixture, the mixture is again raised to the boiling point and the hone immersed in the same for approximately half an hour,

the length of time required to insure a thorough permeating of the hone by the mixture depending of course upon the size and texture of the hone.

When the hone is removed from this bath, it is preferably cooled in a lather formed from the same kind of soap as that employed in making the bath, but said method of cooling the hone is not absolutely necessary and does not form a part of the present invention.

I am aware that hones have been commonly treated with soap and various oils, but by the methods ordinarily in use, this treatment is a surface treatment at the best as the soap or oil does not soak into the hone, remaining merely upon the surface.

My invention consists not in the employment of the soap, but in the employment of the spirits of turpentine as a vehicle, causing the soap to be evenly distributed throughout. the body of the hone.

As a pint of spirits of turpentine weighs approximately 14%- ounces, it will be seen that the above bath is, in fact, a solution of soap in turpentine as there are 1 1% parts by weight of turpentine to 6 parts by weight of soap.

Having thus described the invention what is claimed as new is:

A bath for razor hones comprising 6 ounces of soap dissolved in 1 pint of spirits of turpentine.

In testimony whereof I aflix my signature in presence of two witnesses.
